Hi are your setting working?

Any more information you can give me? I got 2 kits of F4-4266C19D-16GTZA. i can get a combination of 2 to work at 4266 (if i use A2 and b2). If i use a1 and b1 only 2133, if i put in all 4, i only get 2133 also.


thanks for any suggestions

Sorry guys the system was actually unstable with those Voltages. This is a final update with running prime95 for a hour.  Vccio i set to 1.350   and VCCSA is at 1.250 .  XMP enabled 4266 Speeds :) let me know what you think about the voltages. are they safe? i mean the computer would not boot without these voltages.

Hey guys I got the ram to work. both sticks at 4267 with xmp on. I adjusted the VCCIO and VCCSA.
I was wondering is it okay if the VCCIO is at 1.320 and the VCCSA is at 1.200. are those okay voltages for the computer to be running around 8 hours a day?

So I have bought a Fatal1ty Z370 Professional Gaming i7 from Newegg, and it seems that Dram A2 does not boot into proper speeds of ram (4266). I have
G.SKILL TridentZ RGB Series F4-4266C19D-16GTZR . I have tried both sticks on Dram A2 and they do not boot, I have also tried both sticks on B2 and they boot into speed perfectly. The way I configured the ram to boot into windows at those speeds is, I first put Voltage in OC mode, then I went into Dram configuration and tweaked timing with Dram tweaker, then I manually set Dram Frequency at 4266. Doing these steps worked perfectly. Setting XMP profile would not Boot into windows when I tried single stick on A2 or B2 Dram slots. That is another problem I have been encountering that XMP would not boot into windows and I have to do it manually. After heavy testing I know that Dram A2 has a problem booting into high frequency.

So how is it that I stick 1 stick on B2 and it boots perfectly fine, but when I put 1 stick in A2 it does not boot into windows. I have tried both stick on A2 and B2, but XMP or manual input would not boot. maybe it has to do with Voltage, I have not messed with voltage so can someone please tell me their settings with this Motherboard and Ram sticks. Thanx
